Thats a tough place to be, trying to work now and future proof at the same time. My suggestion would be to pick up a used saw, it won't take much looking to find a usable 14" Delta/cast clone to tide you over and you are likely to be able to get most or all of your money back out of it. CL can be great if you are patient, I post great deals on bandsaws from all over the country in the Deals forum. There is a gorgeous 20" Yates Y-120 for $250 in Connecticut that honestly would be worth the drive for you, even considering gas and tuning up the Yates it is still a better saw and saves a chunk of change, even if you had to rent a U-haul.
The other option would be to buy a 513X2F and change out the motor starter and cord and wire it for 120v now and you can switch back later if you care to. Grizzly charges about $175 (IIRC) for motor starter but you can find them cheaper. You will need a 20 amp circuit and assuming you do it will need to be a 20 amp receptacle (instead of the usual 15a duplex) but that is a 10 minute fix.
